While I normally don't concern myself with that issue, I must differ with you that it isn't even a concern. Here's a good example of why-
Using an ipad1 I have been in a year long process of finding apps to obsolete what I do on my Dell laptop so I can take extended trips and leave the laptop at home. It's not just the size of the laptop to tote along compared to an ipad but laptop owners are also harassed more by TSA agents and regulations than a person with an ipad or any tablet for that matter. Many of the apps are and continue to be limited in speed and function.
This past week I have been in search of a decent spreadsheet app for ipad that is compatible with xls files I have on my computer. The app needs to have some basic functions, graphs and editing and numbers formatting. It needs to have an easy way to import and export the spreadsheet file by IP. There are several apps that claim to do this. But the best one for editing seems to be only for iphone screen and the 2X is fuzzy. I tried others but some are greatly limited to just a few rows and columns, don't allow import, or specialized for specific tasks, like checkbook. None are outrageously expensive but buying a half dozen to test and discard can get expensive. But what about speed? The iphone app has great speed for my ipad1 but the resolution of the cells is so fuzzy it is hard to read. The other one I found that competes is designed for the ipad BUT, it is so slow, all I get is a little circle clock ticking away as the spreadsheet moves to a new cell. In addition, it make editing very awkward with special entry box for each cell. I can get my spreadsheets loaded, I can edit them, but the process is extremely slow. So, yes, I do have concern about the "new" ipad3 and whether it's new A5X processor will navigate the ipad app for spreadsheets with the speed of an 80286 computer and display it with adequate resolution so I don't confuse the number 3 with a 5 or 8 in the cell. ipad3 is not just about pretty pictures for me. It IS about the hardware under the covers.
